Compute the following numbers, applying the significant figure rule adopted in this textbook.

a. $\displaystyle 33.3\times 25.4$

b. $\displaystyle 33.3-25.4$

c. $\displaystyle \sqrt{33.3}$

d. $\displaystyle 333.3\div 25.4$

Solution:

Part a

$\displaystyle 33.3\times 25.4=846$ ☚

Part b

$\displaystyle 33.3-25.4=7.9$ ☚

Part c

$\displaystyle \sqrt{33.3}=5.77$ ☚

Part d

$\displaystyle 333.3\div 25.4=13.1$ ☚
